Drug & supplement interaction

Buttercup + Asenapine

Asenapine brand names: Saphris, Secuado.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Buttercup and Asenapine in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Buttercup and Asenapine

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Asenapine and Buttercup in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

Worth understanding: our licensed dataset holds no drug-interaction record for Buttercup at all — not against Asenapine, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

What to actually watch for

No Interaction Found — But Data Suggests Buttercup and Asenapine May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do. One of them is worth acting on rather than waiting out — marked below.

About Buttercup

What is Buttercup?

  • Joint and muscle pain (traditional topical use)
  • Skin conditions and blisters
  • Nerve pain (traditional folk use)
  • Rheumatic complaints

Buttercup refers to plants in the Ranunculus family, which contain an irritating compound that makes the fresh plant toxic to eat and harsh on skin. There is no good scientific evidence that it safely treats any health condition, and it can cause serious irritation and poisoning. We do not recommend using fresh buttercup as a supplement.

Ranunculus spp. · Ranunculaceae · Whole plant, leaves, and flowers (fresh or dried) · Topical preparations, homeopathic remedies, traditional poultices, and dried herb

An interaction check asks whether these two react with each other — it does not ask whether Buttercup is a good idea for someone in your situation. Here is what our Buttercup record says about it on its own.

Buttercup: dosing

There is no established safe dose of buttercup for internal use, and we do not recommend taking it by mouth. The plant is toxic in its fresh form, and standardized supplement products are not available from reputable sources.Any homeopathic preparations are extremely diluted and are a different category of product.

Do Buttercup and Asenapine have any of the same side effects?
Yes — our sources link each of them separately to 2 of the same effects. That is not an interaction: neither changes how your body handles the other.
